Walter-titex 6968741 Screw Machine Drill Bit 0.1496in Carbide

Product Description

The WALTER-TITEX 6968741 is a solid carbide screw machine length drill bit designed for high-precision drilling in demanding industrial and machining applications. The bit measures 0.1496 inches (3.80 mm) in diameter with an overall length of 2.598 inches (66.00 mm) and features a 140-degree drill point angle optimized for fast, accurate entry. A TiNAl (titanium aluminum nitride) coating enhances wear resistance and extends tool life at elevated cutting temperatures. Two flutes provide efficient chip evacuation, and the through-coolant design supports high-speed drilling with internal coolant delivery for thermal management.

This drill bit is suited for machining cast iron, hardened materials, non-ferrous metals, and steel in production environments. Its screw machine length profile — shorter overall length with a reduced flute-to-diameter ratio — provides increased rigidity, making it a reliable choice for CNC machining centers, automatic screw machines, and multi-spindle setups where runout control and hole quality are critical. The straight-cylindrical shank accommodates standard drill chucks and collet holders.

Key Features

• Solid carbide construction for rigidity and wear resistance in hard and abrasive materials
• TiNAl coating reduces friction and extends tool life at high cutting speeds
• 140-degree drill point angle for reduced thrust and accurate self-centering on entry
• Through-coolant capability supports high-pressure internal coolant delivery
• 2-flute geometry with 3xD flute-by-diameter ratio for effective chip evacuation
• Meets DIN and ISO standards with m7 diameter tolerance for consistent fit

Compatibility

Designed as an OEM-style replacement or production-grade drill bit for use in standard drill chucks and collet systems accepting a 6.00 mm (0.2362 inches) straight-cylindrical shank. Belongs to the DC150-03-A1 series. Compatible with workpiece materials including cast iron, hard materials, non-ferrous metals, and steel as specified by the manufacturer.

Installation Notes

Installation should be performed by a qualified machinist or tooling technician. Ensure the machine spindle is fully stopped and locked out before inserting or removing the bit from the chuck or collet holder. Verify shank seating and runout with a dial indicator before beginning a production run. Always apply coolant at the rated pressure when using the through-coolant feature to prevent thermal damage to the bit or workpiece.
